2019-10-02Add {set_options, #{metrics_user_data := Map}}Loïc Hoguin
This allows giving custom metadata to the metrics stream handler. This can be useful to for example provide the name of the module handling the request which is only known after routing. But any user data is allowed. When called multiple times the user data maps are merged.
2018-11-09Add sendfile support to cowboy_req:stream_bodyLoïc Hoguin
It is now possible to stream one or more sendfile tuples. A simple example of what can now be done would be for example to build a tar file on the fly using the sendfile syscall for sending the files, or to support Range requests with more than one range with the sendfile syscall. When using cowboy_compress_h unfortunately we have to read the file in order to send it. More options will be added at a later time to make sure users don't read too much into memory. This is a new feature however so existing code is not affected. Also rework cowboy_http's data sending to be flatter.

2018-10-31Improve a few types, including cowboy_req:req()Loïc Hoguin
2018-10-26Switch cowboy_http2 to the new cow_http2_machineLoïc Hoguin
The new module is a merge of the Cowboy and Gun HTTP/2 state machines. Using a common code will help future developments rather than duplicating the work. A notable change is in how streams are terminated when the handler stops before the body is sent. The cowboy_stream:terminate function is now called only after the body has been sent fully (or the stream is reset in-between), not when the stop command is returned. This will most likely have an impact on metrics but will be closer to reality. I had to comment a broken test in rfc7231_SUITE that was cheating, cheating is no longer possible. This depends on Cowlib master for the time being. A new Cowlib version will be released once both Cowboy and Gun are ported to use cow_http2_machine and I'm satisfied with it.
2017-10-31Add informational responses to metricsLoïc Hoguin
2017-10-20Add a test for metrics with a request bodyLoïc Hoguin
2017-10-20Add experimental metrics stream handlerLoïc Hoguin
It collects metrics and passes them to a configurable callback once the stream terminates. It will be documented in a future release. More tests incoming.
